Be it. known t t I, Kxtr Ivan Lizinsnx, a subject of the Kin ot Sweden, and residing at Xykvam.. weden, proprietor, have invented certain ncw and'use ul Improvements in ilkinEMachineai and I do hereby decline fol wing to be a full. clear. and exact escription 'of the invention. .such as will enable others skilled in the art to which ii nppertaiiii to make and use the iiiimr. rcforcnce being had to the accompanying drawing and to ligure of reference marked tht-reim, which forni a p'art of this slmiticatioii.

The promii'c iuciliuiii. iit'ter having acted upon the milking ilcvicv inl such a manner thnt the uppcr putt of thc teat is compressed so ns to close tht` coniniuuiciition between thc tent und iuldcr. is. led in a suitable manner to thc raising dcvice, which acts upon the milking lei-icc in auch a manner that this tout und the correspondinviliart of thil udiler ure pulled doirnward. ien tlie pressure iuciliuin eeuws to iict. the milking device is ri-turncd into iti-i original position h v thi` iu'tion of gravity or b meiins of a spring.

The milking device adjustn itself nutomntf .ut their extreme inuurd .ically to the teat. if the latter should change position during the milking.

v means of a prenure med The mi device consists of moving in cy indem 11. incloaed in a guard t. irovided nt the forward portion with u .-hcl l2. adapted to receive the tent. l'lw pistons are Aprovided ivith 'pressure ports .11h iii-ting: liuniinst thc tents. he guard l ivitli ilic pistons und cylinders is uplmitml liy mwiuof tivo iivots :2 und u lioiv 3. liriuly vnunet-ml to uiriickct t. so that un iwcilhitinJ inovcincnt on thi-pivot '.2 muy be importi c vliiulcr J is suspended from tlie iird l b v liu'unof thi' pivot, 5 nlijtl i8 timi l Willi n |i.-iuu t'. nliuttiiii:` ugiiinst tie lioiv 3. The

' uppoi' vmic of the pistons 10 having been Lnohwl forivuril. iiirlis conducted by a pipe 'i which will thon i'oinniu|iiciite with tlie iip ut thv milking device israiasd and the forwur'l purt of tho some lowered became the liriicket 4 cannot move in a vertical plane.-

'llie cylinders comiminicato with each other hy mcuns of 'luinuels 16 and 17 bored iii the cylinder wall.; 'hen the pistons or! position, the said chunncls iiiiclosed .by the Pidonl, but when. the pistons nrc nt their extreme outward nitions. the channels are By this lt'- riingcinent. the pressure medium will be caused totill the three cylinders so as to act successively on the pistons threin.

When the uit` is withdrawn from the milking device through the pipo 14, it is also withdrawn from the cylinder 9 and theA rear part of the guard l consequently will be lowered to its original position by means of its' Wei vllt.

'hat I clnim is: 1. In a niilkinginachine, the combination of a stationary bracket,a mi suspended therein and adapted to oaci to los Il emessi in a vertical plane, and means located be. tween thc said bracket and organ and adapted to oscillate said organ.

2. In a milking machine, the combination of a stationary bracket. a milking o i'rnu auiipeudcd therein and adapted to oscil ate in a vertical plane. and expansible menus lol.

adapted 'to oscillatc about aid i cated beta-een the said bracket aud the end of the said 'organ aud adapted to oacillate the lattert t 2l. ln a uiilkiiig'uiiachiiie, the combination of'a stationary bracket, pivots secured tliereto, a milking organ adapted to oscillate about said pivots iii a vertical plane, and an expansible body located between the said bracket and the said organ and adapted to oscillate tbe latter.

4. In a milking,l machine, thecoiubiuatiouof a atationa bracket, pivots secured thereto, and a mil ing organ suspended by said \pivota and adapted to oscillate in a vertical plane and an expansible body, comprising a piston located between the said bracket and :aid organ and adapted to oscillate the lat- 5. In a milking machine a stationary bracket, pivots fastened therein, a milking organ adapted to oscillate about said pivots in a-'vertical plane, a cylinder having its end secured to the end of said orga ton arranged in said cylinder and abutting :ainat the bracket, said piston being adapt- -to oaeillate said organ.

6. In a milkin machine, the combination of a atationary racket having pivota secured thereto, a milking organ ada ted to oncillate about said pivots iu a vertice plane, u c vlinder having its ends secured to the end ol' said organ. a piston arranged in said cyliudcr and abutting.r against the bracket and `a lluid e-upply nandapis-v pipe communicating with .said c vliudcr au.. adapted to move thc piston thereinto oscillate the said organ. i, lu a milking machine a stationary bracket having pivots. a milking organ ivotii in ii vertical plane. a pluralityl of cylinders (11) communicating with euch other, a piston arranged in cach of said cylinders anda cylinder (il) having its cud secured to the end of said organ. said cylinder 0) communicating with one of' tbc said rst-mentioned cylinder# (ll) anda piston in said cylinder (9) abutting a 'ainsi the said bracket and adapted to oscil utc the said organ.

. ln a milking machine the combination fof a stationary bracket having pivots secuicd thereto. a guar-l provided with a s ace for thc teni. and adapted to oscillate a ut said pivots in a vertical plane, and a plurality o intercomiuunicatinpz,cylinders inclosed in said guard. pistons arranged in said cyl` inders adapted to be successively brought iii contact with the teat. a cylinder secured to the cud of said guard, a piston arranged in said latter cylinder and abutting a minst the said bracket, the said latter cy inder communicating with one of thc interci'nuinu-` uicating cylinders.

In testimony, that I claim the foregoing as my invention, I have signed my name iii presence of two subscribing witnesses.
